CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 351,381, dated October26, 1886.

Application filed August 21?, 1886. Serial No. 212,104. (NomodeL) To allwhom it may concern:

Be it known that I, SIDNEY DoDcnKrNG, of Pittston, in the county ofLuzernc and State of Pennsylvania, have invented certain new and usefulImprovements in GanCouplings; and I do hereby declare the following tobee full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in cancouplings.

The object is to provide a coupling in which themovement of the parts inreleasing the link will positively lock the parts in a position toautomatically couple. A further object is to provide a link-controllerwhich shall form a part of and be operated by the same lever as thepin-operating bar. A further object is to provide a coupling in whichthe operating lever and rod may be located either below or above thedraw-head, and in which the withdrawal of the draw-head by accident orotherwise will leave the working parts intact. A further object is toprovide a coupling which will withstand the punishment to which they areoften subjected in practice, and in which the number of parts shall bereduced to.a minimum, and capable of being supplied at a low initialcost.

\Vith these ends in view my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical section through oneof the drawheads, showing the parts in position to receive the link.Fig. 2 is a similar view showing the parts in coupled adjustment, andFig. 3 shows the position of the parts to retain the links although inreleased adjustment.

A represents the draw-head provided with a hopper or bell-shaped mouth,a, as is customary. The draw-head extends downwardly quite a distancebelow the mouth, and is provided with two vertical perforations, B and1), extending through the longitudinal axis of the drawhead, a shortdistance apart, the former serving as a guide and bearing for thecoupling-pin C and the latter as a guide and bearing for thepin-operating bar D.

The coupling-pin C is suspended from. the

end of a forwardly-extending arm, 0, attached to the upper end of thebar D. The arm 0 may be attached rigidly to the head of the couplingpinand removably secured to the upper end of the bar D; or it might beremovably or securely attached to both, or rigidly attached to the barand removably attached to the pin. The first-named constructionis,however, preferable, because of the convenience it affords in removingthe bar and pin from the drawhead.

A gravity pawl or dog, E, is loosely suspended from a pivotal bolt, 0,set in the pin-operating bar D, and is so located that when the bar D iselevated sufficiently to release the pin 0 from the link F the pawl ordog E will be free to swing forwardly far enough to admit of its forwardend engaging the top of the wall G between the perforations B and b, andthereby preventing the drop of the bar D. Furthermore, the forward swingof the pawl or dog E, which would ordinarily be effected by gravityalone, is insured against any possible failure through sticking orbecoming clogged by foreign substances by the engagement of its rearupper corner, c, with a beveled shoulder, e, which positively swings itforwardly when the bar D is elevated.

The approaching link effects a coupling by striking against theforwardly-extending portion of the pawl, knocking or pushing the pawloff from its seat and allowing the coupling-pin and pin-operating bar tofall into the position shown in Fig. 2.

The link-controller H consists of a bracketlike piece formed integralwith or rigidly secured to the front side of the operating-bar D, itslower end being slightly concave to cause it to conform to theordinarily rounded shape of thelink in cross-section. \Vhen the pin andpin operating bar are in depressed adjustment, as shown in Fig. 2, thecontroller rests on the end of the link, and when drawn down on the linkserves to elevate the outer end of the link, and when elevated allowsthe outer end of the link to drop, thereby enabling the operator to holdit at such a height as to cause it to enter the mouth of the oppositedraw-head.

The operating-lever I is sccuredat one end to a rock-shaft, K, journaledunder the end of the car and provided with cranked ends terminating inhandles k. The operating-lever I extends forwardly from the shaft Ktoward the draw-head, and extends through an elongated vertical slot, L,formed therein and through or into a socket, Z, formed in the lowerportion of the pin-operating bar D. Thus, Whenever from any-cause thedraw-head is pulled from the car, the end of the lever I' outfurthcrattention to the operating shaft andv lever, and when withdrawnthe parts will assume the position shown in Fig. 2, ready to effect acoupling.

The operating shaft and lever might be located above the draw-bar, iffound desirable,

. and many slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not wish to limit myselfstrictly to the construction herein set forth; but

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a car-coupling, the combination, with a pin and a pin-operatingbar located behind the pin, of a link-controller attached to the frontface of the bar, and a device for moving the bar downwardly for thepurpose of bringing the controller down into COlliiilGhWltll the link,substantially as set forth.

2. In a car-coupling, the combination, with a coupling-pin and apinoperating bar, and devices located below the draw-head for operatingsaid bar, of a gravity pawl or dog pivot- 7 ally secured to thepin-operating bar, adapted to lock the pin in released adjustment,substantially as set forth.

a draw-head provided with vertical openings,

of a coupling-pin and pinbperating bar adapted to be reciproeated insaid openings-one in eaehand a gravity-dog pivoted to the pinoperatingbar and located wholly within the draw-head, substantially as set forth.

5. "In a car-coupling, the combination, witha pin-operating baradaptedto be reeiprocated in the draw-head, of a gravity-pawl pivoted to thebar and adapted to engage the drawhead, whereby it is positively swungforward when the bar is raised, substantially as set forth. p

6. In a car-coupling, the combination, with a pin-operating bar seatedin the draw-head, of a bar-operating lever located below the draw bar,substantially as set forth.

7. The combination, with the draw-head and the coupling-pin andpin-operating barlocked together, of a lever entering the draw-head.from below the draw-bar and removably attached to the pin-operatingbar, substantially as set forth.

8. The combination, with the pin-operating bar, of a gravity-dog pivotedthereto, adapted to pass the link-when the bar is raised and engagethelink in its fall, thereby holding the pin in released adjustment withlink in the draw-head, substantially asset forth.

In testimony whereof- I have signed this specification in the presenceof two subscribing witnesses.
